TRANSFER DEVICE Filed OCT.. 9, 1929 l'Nvf/vmk @mamy Www/M Patented Jan. 10, 1933 UNITED STATES PATENT OFFHCE PAUL O. UNG'ER, OF SYRACUSE, NEW YORK, ASSIGNOR TO MCMILLAN :BOOK COMPANY, OF SYB'ACUSE, NEW YORK, .A CORPORATON 0F NEW YORK TRANSFER DEVICE Application filed Gctober 9, 1929.

This invention relates to a new and improved transfer bar.

Although my invention is adaptable land may be used in various ways7 it is particularly designed to temporarily secure together certain of the leaves of a loose leaf binder when it is desired to remove them from the binder for any purpose such as transferring them to another binder or for the purpose of working on them while the binder with its remaining leaves can be kept in use.

The main object of my invention 1s t provide a light and easily manipulated device in which lea-ves of a loose leaf binder may be quickly confined and securely held.

Another object is to provide a device of such construction that without adjustment, it may be used to secure varying numbers of sheets.

Other objects and advantages relate to the size, shape and arrangement of parts all as will more fully appear from the following description taken in connection with the accompanying drawing in which:

Figure 1 is a perspective view of the preferred form of my device with a plurality of loose leaves secured therein.

Figure 2 is a section on line 2 2 of Figure 1.

Figure 3 is a section on line 3 3 of Fig.- ure 2.

Figure 8 is a fragmentary perspective view of another modified form of catch.

Figure 9 is a section on line 9 9 of Figure 8.

Figure 10 is an inverted view Aof the form shown in Figure 8.

My device consists of a bottom bar 1, having in spaced relation to one end, a circular aperture 2 with a slot 3 extendingtherefrom a short distance towards the end of bar V1.

The width of slot 3 is less than lthe diam- Serial No. 398,44?.

eter of aperture 2. In spaced relation to aperture 2, I provide an upwardly extending headed post t. Between such post 4 and the adjacent end of bar 1 is provided a vertically extending'post 5. c

Between post 5 and adjacent end of bar 1 is provided an aperture 6. Bar 1, as may best be seen from Figure 3, is preferably slightly V-shaped in cross section to give it added strength and rigidity so that it will rnot become distorted during use.

A top bar 7 of approximately the same length and slightly narrower than bar 1 has in its forward end a slot 8 of the same width as slot 3 but of a length equal to the combined length of slot 3 and aperture 2.

In spaced relation to slot 8 is provided an aperture 9 through which post 11 extends. Adjacent post s and between it and post 5 is provided on bar 7 a downwardly extending transverse rib a From rib L the end of bar 7 is bent upwardly away from bar 1 and in such upwardly bent end of bar 7 is provided a slot 10 through which post15 extends.

As perhaps may best be seen from Figure 4f, the bottom surface of bar 7 is preferably roughened as shown at t so that there may be no tendency of a sheet to slip on bar 7.

A slidable button 11 is positioned yin slots 3 and 8, the upper head 12 on button 11 being larger in diameter than the width of slot 8 and the lower head 13 of button 11 being greater in diameter than the width of slot 3 but being slightly less in diameter than the diameter of aperture 2 so that when button 11 is moved inwardly to bring head 13 in registration with aperture 2, the head 13 will pass through aperture 2 to disconnect the ends of bars 1 and 7.

When head 13 is again passed through aperture 2 and button 11 is moved forwardly into slot 3, the ends of bars 1 and 7 will be locked together.

Bar 7 is preferably made of spring-metal normally of a shape indicated by dotted lines in Figure 2 so that when the ends of bars 1 and 7 are secured together by means of button 11, the inherent resiliency of bar 7 will cause the same to be pressed tightly against bar 1.

Y So that bars 7 and 1 may relatively adjust themselves to accommodate different numbers of sheets between them they are held together at the end opposite to that carrying the button 11 by means of a coil spring 14 which encircles post 4 and has one end abutting against the head on post 4 and the other end abutting against the upper surface of bar 7.

The end of bar 7 adjacent rib -ais bent upwardly so that when the opposite ends of bars 1 and 7 are permitted to separate by the removal of button '11 from bar 1, a downward pressure on the end of bar 7 will cause the same to be moved about the rib -a as a fulcrum to further separate bars 1 and 7 to facilitate the introduction therebetween of loose leaves.

The post extending through the slot 10 is provided so that bars 1 and 7 will be maintained in alinement when they are not locked to ether by button 11.

'he aperture 6 is rovided so that the device may be convenient y hung on a hook or nail when not in use.

In Figures 5 and 6, I show a modified form of latch comprising a double-headed post ositioned in slots 2 and 8 with its bottom ead 16 of approximately the same size as head 13 on button 11.

On the upper surface of bar 7 and slidably mounted on post 15 is provided a U-shaped member 17 having its upper ends 18 and 19 curved outwardly and downwardly to provide a convenient grip for the fingers of the operators hand.

A spiral spring 20 encircles post 15 and has its lower end abutting against the upper surface of member 17 and its upper end abutting against the underside of head 21 on post When it is desired to place head 16 in registration with aperture 2 so that post 15 may be removed from bar 1, the U-shaped member 16 is sped with the fingers and pulled upw ,Y y, the post 15 being held in position by thethumb ofthe operator.

This raising of member 17 against the pressure of spring 20 will permit post 15 to be easily moved from slot 3 into registration with aperture 2, and post 15 may be again placed in registration with aperture 2 and slot 3 by a like manipulation of parts.

In Figures 8, 9 and 10, I show another modified form of latch for which is provided an aperture 22 in bar 1. From aperture 22 extend opposed slots 23 and 24.

Bar 7 is provided with an aperturer 25 through which extends a post 26 having on its lower end a transverse bar 27 of a size and shape to pass readily through slot-s 23 and 24 and aperture 22 when such bar 27 is in registration with such slots 23 and 24.

'The length of bar 27 is greater than the diameter of aperture 22 so that if post 26 carrying bar 27 has its lower end moved downwardly beneath the under surface of bar 1 and is then rotated one-fourth of a revolution, the ends of the bar 27 will contact with the under surfaceof bar 1 so that post 26 cannot be removed from bar 1 and the latter will be locked to bar 7.

For the purpose of holding bar 27 firmly When it is desired to use my device for the purpose of transferring leaves from a loose leaf binder. the binder covers are opened.

The latch at the front end of the device is then released so that the bars 1 and 7 will be allowed to separate.

The bar 1V is then inserted between the leaves having on top of it the leaves which it is desired to transfer. The bar 7 is then pressed downwardly on top of the leaves to be transferred and the latch at the forward end of the device is engaged to secure bars 1 and 7 together. 4

The under surface of bar 7 being roughened. as shown at -b, such bar will grip the upper leaf securely and there will be no tendency for such leaf and the leaves beneath it to slip out of position.

Similarly, the under surface of the bottom leaf will be securely held due to the fact that the upper surface of bar 1 is in angular relation on each side to the leaf neXtto it.

. The upper bar 7 being of spring-metal and so shaped that it is normally curved downwardly in the middle will, through itsV inherent resiliency, press downward against the sheets to grip the sheets tightly between Vitself and baril which is rigid.

The rear end of bar 7 being held against bar 1 by means of spring 14, the device is self-adjusting so far as the number of leaves to be confined in it is concerned because the rear end of bar 7 may move upwardly against the pressure of spring 14 to give more space between bars l and 7 if the number of leaves to be transferred requires such space.

In Figure 1, I have shown my device in position on a plurality of leaves 31 which leaves are provided with the customary apertures 32 through which the posts or prongs of the Ybinder extend.

When the device is in position on the leaves to be transferred, the posts or lprongs of the binder are opened and the leaves so confined in the device are removed from such posts or prongs. They ma then be transported to be used as desire The leaves 31 being securely held in the device, the apertures 82 will be held at all times in alinement so that when it is desired to return the leaves to the binder from which they were taken or to place them in anothersimilar binder, such action is easily done due to the fact that all of the apertures 32 in the leaves 31 are in alinement and the leaves may be simultaneously placed on the posts or prongs.

I have here shown particular parts indin cated as being of certain sizes and shapes, but it will be understood that such sizes and shapes may be varied to a considerable eX- tent without departing from the spirit of my invention, for although I have shown and described a specific structure and form and arrangement of parts, as exemplications of embodiments of my invention, I do not desire to restrict myself to the exact size, shape or relation of parts as various changes may be made within the scope of the appended claims.
